Hello. I need help with my project.
My project is about managing the lights in a room. I have a main light (220v), a 12V light and a strip of LEDs (12V).
Everything works perfectly, the only drawback is that the system disconnects. The Blynk APP connection is disconnected. I think I have detected the problem, it may be the physical switch that has noise and makes the system disconnect. I would like to know how to solve it. Thank you.

{
int pinValue = param.asInt();
if (pinValue == 1) {

digitalWrite(LM,LOW);
}
}
BLYNK_WRITE(V3) //lectura del botón virtual V2
{
int pinValue = param.asInt();
if (pinValue == 1) {
apagado=1;
}
else {
apagado=0;
}
}
void prendido()
{
if(apagado == 0)
{
digitalWrite(D5,LOW);
digitalWrite(D6,LOW);
digitalWrite(D7,LOW);
}
}
void loop()
{
Blynk.run(); // Run Blynk
timer.run(); // Run SimpleTimer
}
This project is still in the testing phase. The Serial library will be removed when finished. The checkPhysicalButton () function is in charge of synchronizing the physical switch with the virtual one in the Blynk APP.
The prendido function is created so that when you want to use the led strip, you have to press a virtual switch in the APP.
Here is the connection diagram
